Using Data Sets That Have One-Level Names

If you use an ODBC application such as Microsoft Access that exports databases using one-level names, you should use the ODBC Data Source Administrator to define a User library. SAS usually places any data set that has a one-level name in the Work library, which is deleted at the end of the SAS session. But, if a User library has been defined, SAS places all one-level named data sets in the User library, which is saved at the end of the SAS session. In a multi-user environment, multiple client connections to a SAS server can each have its own User library defined.
